Tom Clancy’s Rainbow Six Siege Reveals Year 6 Season 4 High Calibre

Published Date :

Today, Ubisoft revealed High Calibre, the fourth and final season of Tom Clancy’s Rainbow Six Siege Year 6. This new season includes a new Operator, Thorn, coming from Ireland and equipped with Razorbloom Shells and bearing a brand-new weapon, the UZK50Gi, in addition to the reworked Outback map and many other updates.

In High Calibre, players will discover a brand-new Defender, Thorn, equipped with Razorbloom Shells: throwable proximity devices that, once triggered, initiate a timed detonation. If enemy players don’t get out of the area of effect on time, they will receive damage at the end of the fuse timer. Thorn is a medium speed, medium armor operator who can be equipped with either the new UZK50Gi or the M870 as a primary weapon and with the 1911 TACOPS or the C75-AUTO as a secondary weapon.

In addition, the Outback map has been rebuilt to improve balancing and player comfort. Both the main building and its exterior have been modified to allow the attackers to create and execute more effective strategies. In addition, new exterior soft walls have been added to the building, and some areas have been refurbished and cleaned up to remove junk and provide better lines of sight and balance.

Additional updates coming with High Calibre include:

  • Choosing team colors between blue, orange, or red
  • Balancing updates (Finka, Echo, and Mozzie’s drones, bulletproof cameras update, new rule for cameras placed outdoors)
  • New customization features on Operators’ Cards, victory dances, colors, and more.
  • New HUD
  • The new version of the Streamer Mode soft launch for a limited number of creators is coming during the season

The Test Server for High Calibre will go live on 9th November. The Test Server format has been updated and will now be open at three separate times throughout the season and content will be split into three different releases: the seasonal release TS which contains the content that will be shipped with the season, the Lab TS release which includes experimental content that will be used to test features in early production, and the TS balancing release which contains the Operator and other balancing changes.

Players are invited to submit the issues they encounter on the Test Server on the updated R6 Fix platform here. This new platform is now easier to navigate in and offers new features such as the search feature or the possibility for players to track updates on bugs they report for more transparency. In addition, players can earn twice as many Battle Pass points from 12th – 15th November.
